Design of Signal Analysis System Based on Audio Multimodal Research
This paper accurately locates real data through statistical analysis of NSP mode files,analyzes the structure,encoding features,and influencing factors of WAV mode files;fully considers the number of channels,sampling frequency,and PCM sampling bits to realize the conversion of different mode formats,and designs a sig-nal analysis system based on audio multimodal research.The experiment conducts a comprehensive comparative a-nalysis from the aspects of file internal code,file parameter information,signal acoustic waveform and subjective auditory perception to verify the effectiveness and practicality of the system.
